Technique to replace the high beam indicator bulb?

I use #4 a lot. In reality though, I pull the cluster, clean & test everything on the bench & reinstall the cluster. It usually works fine for a month or so then something loosens up and a bulb here & there goes dim... I can't win.
Yep! Brighten up those terminals, replace all the bulbs, clean both sides of the bezels, paint the needles! LOL
